Abstract
The present invention relates to aqueous compositions comprising one or more silicones and a synergistic combination of anti-microbiological agents, to a process for preparing the aqueous compositions, and to the use of said aqueous compositions, in particular, for the manufacture of home care articles, household cleansing articles, fabric articles, cosmetic articles, hygienic articles, medical articles etc.
Claims23
An aqueous composition comprising one or more silicones, and
- a) at least one compound of the general formula (1)
- wherein
- n is 0 or 1,
- R1, R1* and R1** are independently selected from the group consisting of hydrogen, a linear or branched C1-C9 alkyl group, and a linear or branched C1-C9 alkyloxy group, and
- R2 is a linear or branched divalent C2-C5 alkyl group,
- and
- b) at least one compound selected from general formula (2)
- wherein compound (2) has 5 to 22 carbon atoms, and wherein
- R3 is selected from the group consisting of hydrogen, a linear or branched C1 to C12 alkyl group, a linear or branched C1 to C12 alkylaryl group, an aryl group, a linear or branched C1 to C12 alkyloxy group, a linear or branched C1 to C12 alkylaryloxy group, and an aryloxy group, and
- R4 and R5 are the same or different and are selected from the group consisting of a linear or branched C1 to C12 alkyl group, a linear or branched C1 to C12 alkylaryl group, an aryl group, or
- R4 and R5 together form an optionally substituted ring system with at least 5 carbon atoms, and
- c) optionally one or more compounds selected from the group consisting of the general formulae (4) and (5)
- wherein
- R6 and R7 are either both hydrogen or one is a methyl group and the other is hydrogen and
- R8 is selected from the group consisting of a linear or branched C6 to C14 alkyl group, a linear or branched C6 to C14 alkyloxy group, a linear or branched C6 to C14 alkyloxyalkyl group, a linear or branched C6 to C14 alkylaryl, a linear or branched C6 to C14 alkylaryloxy and aryloxy group.
An oil-in-water emulsion comprising 5 and 40 weight-% of one or more silicones based on the weight of the oil-in-water emulsion, and
- a) at least one compound of the general formula (1)
- wherein
- n is 0 or 1,
- R1, R1* and R1** are independently selected from the group consisting of hydrogen, a linear or branched C1-C9 alkyl group, and a linear or branched C1-C9 alkyloxy group, and
- R2 is a linear or branched divalent C2-C5 alkyl group,
- and
- b) at least one compound selected from the group consisting of the general formulae (2) and (3)
- wherein compounds (2) has 5 to 22 carbon atoms, and wherein
- R3 is selected from the group consisting of hydrogen, a linear or branched C1 to C12 alkyl group, a linear or branched C1 to C12 alkylaryl group, an aryl group, a linear or branched C1 to C12 alkyloxy group, a linear or branched C1 to C12 alkylaryloxy group, and an aryloxy group, and
- R4 and R5 are the same or different and are selected from the group consisting of a linear or branched C1 to C12 alkyl group, a linear or branched C1 to C12 alkylaryl group, an aryl group, or
- R4 and R5 together form an optionally substituted ring system with at least 5 carbon atoms,
- and
- c) optionally one or more compounds selected from the group consisting of the general formulae (4) and (5)
- wherein
- R6 and R7 are either both hydrogen or one is a methyl group and the other is hydrogen and R8 is selected from the group consisting of a linear or branched C6 to C14 alkyl group, a linear or branched C6 to C14 alkyloxy group, a linear or branched C6 to C14 alkyloxyalkyl group, a linear or branched C6 to C14 alkylaryl, a linear or branched C6 to C14 alkylaryloxy and aryloxy group.
